After much procrastinating (and generally just assembling and painting whatever models looked cool, as opposed to writing a list and then painting it) I've finally written a 1500-point Deathwatch list. Definitely open to suggestions, as I haven't actually played any games of the new edition yet.
Note: for anything DW use that listed under the Space Marine wargear list (as opposed to explicitly Deathwatch) I'm using the new Codex points values. This primarily applies to that 8-point drop in powerfist costs.
EDIT: After some feedback elsewhere I've modified the list slightly to add some stormshields. Yes, they're expensive for DW, but probably worth it.

The idea is that Kill Team 1 deploys inside the Corvus and acts as the main assault force; fly in, disembark, charge ASAP. Kill Team 2 is the mid-range component, hanging back and shooting from mid-range or charging in as-needed. Kill Team 3 is the long-range shooting component, hanging back in cover and babysitting at least 1 of the teleport homers. The Razorback hangs around near them to add some extra long-range anti-vehicle firepower.
